Just bought a couple of the new Playtive Junior gliders from Lidl. Smaller than the one we're all familiar with, weighing in at just 45g Should be possible to electrify this one well under 250g AUW (I never managed to get under 250g with the larger one). There's a 9g ball-bearing glued under the cockpit instead of the steel bolt in the earlier model. It'll need a very small motor up front to balance this one.
